Question

A 120-V rms voltage at 60.0 Hz is applied across an inductor, a capacitor, and a resistor in series. If the rms value of the current in this circuit is 0.600 A, what is the impedance of this circuit?

Answer 1

Answer:

The impedance of this circuit is 200 ohm.

Explanation:

Given that,

rms voltage = 120 v

Frequency = 60.0 Hz

rms current = 0.600 A

We need to calculate the impedance

Using formula of impedance

$Z=\dfrac{V_{rms}}{I_{rms}}$

Where, $V_{rms}$ = rms voltage

$I_{rms}$ = rms current

Z= impedance

Put the value into the formula

$Z=\dfrac{120}{0.600}$

$Z=200\ Omega$

Hence, The impedance of this circuit is 200 ohm.
